The International Society for Animal Genetics (ISAG) Equine Genetics and Parentage Testing Standardization Committee is offering a special 2026 off cycle Equine SNP Comparison test. This off-cycle test is being performed to meet the request of the industry, specifically, an official request was received by the committee and approved.   This will  enable SNP parentage testing in Thoroughbreds, who require a rank 1 for parentage testing ahead of the next scheduled CT.  That being said, the CT is open to any institutional member interested in participating and a mix of breeds are anticipated to be included with the sample set shared by the duty lab.

The standard 2026-2027 comparison test process will still occur with the application process opening later this year.

The deadline for all applications is February 24, 2026.
Please note that submitting applications after the deadline is not possible.

In order to participate in this year off cycle comparison tests, laboratories need to be paid institutional members of ISAG for 2026

You will need to enter your institutional member login and password in order to access the application forms. Individual ISAG members will not have access to the application forms.

ISAG will organize the shipping of samples for this test using FedEx as the courier. A standard charge of USD 135 will be invoiced for this off cycle CT, to cover the costs of processing and shipping samples. Shortly, after the application deadline, you will receive an invoice.

ISAG must receive processing and shipping cost payments before your participation in the test will be accepted or samples shipped.

Please review the Critical Duty Lab Notes for Shipping and Receiving Samples Here.

The deadline to request a second shipment of samples will be May 1, 2026. Laboratories requesting additional samples will be assessed a USD 210.00 processing fee per set of additional samples. These samples will ship no later than May 7, 2026.

Please contact the ISAG administrative office at isag@assochq.org for technical problems related to the application forms.
